Roger Bannister, a medical man by trade, pursued his goal of becoming history’s first four-minute miler like a laboratory experiment, pacemakers being integral to the British medical student’s plan.

Bannister’s foil, had assiduously avoided pacemakers as he tried in vain to beat Bannister to the four-minute barrier.
Apparently Landy never outwardly criticised Bannister for using pacemakers, but others in his circle did.
There was no provision against rabbits at that time, only the de facto belief in some quarters that they were against the spirit of competition.

Bannister knew, as runners have always known, that pace-making leads to faster times, not necessarily victories, but triumphs over the clock.

By not using pace-setters Landy missed a trick though.
Maybe it was an over-confidence bias in his own capability and he didn’t want help on the track.

It’s curious though because he would have sought all kinds of help in everything else from training to nutrition and yet the one final thing that would have helped him he chose not to use.

Just goes to show that if you want something you’ve always got to go the extra mile.
